Object Management Group (OMG) Specifies open standards for every aspect of distributed computing Multiplatform Model Driven Architecture (MDA) Unified Modeling Language (UML) models

UML UML is the industry’s standard for representation of analysis and design. Seeks to define concepts, to establish notation for communicating those concepts, and to enforce the related grammatical rules for construction software models, allowing for automated tool support. The set of tools involves a rich set of graphical elements, including notation for classes, components, nodes, activities, ports, workflow, use cases, objects, states, and the relationship between all these elements.

UML Diagram Types Activity diagram – a workflow diagram describing an algorithm in terms of user actions and corresponding decision points Class diagram – shows the internal structure of a program, including the name of all internal classes, their methods and variables; also shows calling and inheritance relationships between classes Collaboration diagram – shows the sequence of the messages that objects in a group send to one another while processing an algorithm Implementation diagram – a high-level diagram showing how various software modules (libraries or application) and hardware components (servers) of a computing system are organized

UML Diagram Types Sequence diagram – describes an algorithm by organizing it into a series of steps arranged in chronological order Statechart diagram – a state machine diagram showing the various conditions a system can be in and how that system moves from one state to another Use Case diagram – shows the tasks that make up a system and the people who interact with these tasks
